3310. Pluto

Pluto, also called Pluto the Pup, is a cartoon character created in 1930 by Walt Disney Productions. He is a light brown (most recently yellow), medium-sized, short-haired dog. Unlike Goofy, Pluto is not anthropomorphic beyond some characteristics such as facial expression. He is most often the companion of Mickey Mouse, although he first appeared as Minnie Mouse's dog Rover in the film The Picnic (1930). Officially a mixed-breed dog, Pluto was likely designed after a pair of Bloodhounds from the film The Chain Gang (1930).
Pluto debuted in animated cartoons and appeared in 24 Mickey Mouse films before receiving his own series in 1937. All together Pluto appeared in 89 short films between 1930 and 1953. Several of these were nominated for an Academy Award, including The Pointer (1939), Squatter's Rights (1946), Pluto's Blue Note (1947), and Mickey and the Seal (1948). One of his films, Lend a Paw (1941), won the award in 1942. Because Pluto does not speak, his films generally rely on physical humor. This made Pluto a pioneering figure in character animation, which is expressing personality through animation rather than dialogue.
Like all of Pluto's co-stars, the dog has appeared extensively in comics over the years, first making an appearance in 1931. He returned to theatrical animation in 1990 with The Prince and the Pauper and has also appeared in several direct-to-video films. Pluto also appears in the television series Mickey Mouse Works (1999–2000), House of Mouse (2001–2003), and Mickey Mouse Clubhouse (2006–present).

According to various sources, Pluto is based upon a pair of Bloodhounds from the film The Chain Gang (1930). The only observable difference between these dogs and the early Pluto are the ears, which on Pluto are black.
A month and a half later, Minnie Mouse owns a dog named Rover who comes along with her and Mickey on a picnic. The dog is virtually identical to Pluto. The dog first appears as Mickey's companion the following year in The Moose Hunt where Pluto accompanies Mickey on a hunting trip.
Several months had passed between the naming of what was believed to have been the ninth planet, Pluto, on March 24, 1930, and the attachment of that name to the dog character. Venetia Burney (later Venetia Phair), who as an eleven-year-old schoolgirl had suggested the name Pluto for the planet, remarked in 2006: “The name had nothing to do with the Disney cartoon. Mickey Mouse's dog was named after the planet, not the other way around.” Although it has been claimed that Disney named the dog after the planet, rather than after the mythical god of the underworld, this has not been verified. Disney animator Ben Sharpsteen said "We thought the name [Rover] was too common, so we had to look for something else. ... We changed it to Pluto the Pup ... but I don't honestly remember why."
Pluto was initially a minor character until 1934, when Disney animator Norm Ferguson gave the dog a key role in the cartoon Playful Pluto. Pluto becomes entangled with a sticky piece of flypaper, and Ferguson expanded the sequence significantly. The segment became a classic, demonstrating how Disney artists can take a simple circumstance and build humor through a character.

Pluto is normally a non-speaking character. A significant departure from this was The Moose Hunt (1931) which was produced before Pluto's characterization had been clearly defined. As Pluto made more appearances, it became common that he would not speak, but only vocalize in barks and grunts. Other ways of communicating Pluto's thoughts occur through his facial expressions, and sometimes through the use of a shoulder angel/devil who speak directly to Pluto. (Mickey's Elephant, Lend a Paw).
Pluto is generally a cheerful and adventurous dog, although he can be given to sheer panic when confronted with something unknown. Common themes in Pluto's stories involve him becoming jealous of Mickey getting another pet (Mickey's Elephant, Lend a Paw, Mickey and the Seal), Pluto accidentally and unwittingly swallowing something and panicking when he realizes it (Playful Pluto, Donald and Pluto), Pluto getting entangled with something inanimate, or Pluto being pestered by a smaller animal (Private Pluto, Squatter's Rights). In many of his appearances with Mickey, Pluto will get himself into trouble and cause Mickey to get angry at him. Mickey however, often cheer up quickly, often telling Pluto "I can't be mad at ya."
Pluto sometimes appears with other regular animal characters. His friends include Fifi the Peke, Dinah the Dachshund, and Ronnie the St. Bernard Puppy. Other animals he is less friendly with include Salty the Seal, Butch the Bulldog, Figaro the Kitten, Chip 'n Dale, Spike the Bee, Ol' Benttail the Coyote, Milton the cat and other characters. In Disney's 1937 animated short Pluto's Quin-Puplets, Pluto has a son who is simply referred to as "Pluto Junior." In the 1946 animated short Pluto's Kid Brother, Pluto has a younger brother named K.B.
